About the ConnectCore® 8X

The ConnectCore 8X is a secure and extremely cost-effective connected System-on-Module platform.

Its innovative Digi SMTplus™ (patent-pending) surface mount form factor allows you to choose

simplified design integration leveraging proven and easy-to-use edge-castellated SMT technology, or a

versatile LGA option for ultimate design flexibility with access to virtually all interfaces.

Built on the NXP i.MX 8X application processor, the module is the intelligent communication engine for

today’s secure connected devices. It integrates dual-Ethernet and pre-certified dual-band Wi-Fi

(802.11a/b/g/n/ac) with dual mode Bluetooth 4.2 connectivity.
